Method of regulating power in a high-intensity-discharge lamp |
摘要 |
A system and method of controlling power to a high-intensity-discharge lamp is provided. A voltage sensor determines voltage across the lamp. A current sensor determines current through the lamp. A control circuit approximates lamp power based on input from the sensors, compares the lamp power against a desired level, and regulates lamp power based on the comparison.
